Bearings support relative motion; guides and ball screws provide constrained or driven movement. Those product capabilities do not establish manufacture of the robot’s load-bearing structural links.
Why are some parts missing company matches?
The current universe has no verified direct match for the illustrated structural link. We show that gap rather than treating any bearing supplier as a structural-link manufacturer.
NSK brings an established robot-bearing business. THK and HIWIN offer focused linear-motion exposure; Schaeffler combines bearings with a growing humanoid component portfolio.
Open each company below for its source and limitations. Sector membership does not establish a confirmed supply contract.
Inside the assembly
Structural link & mounting points
The rigid link joins mechanisms and carries forces between them. A bearing supplier is not automatically a manufacturer of this structural link.
Stock-link scope: No standalone structural-link supplier was verified in this universe. Bearing and actuator expertise alone does not establish chassis manufacture.
No verified direct company match in the current universe.
Outer bearing race
The outer race locates the bearing in its housing and provides one of the rolling-contact surfaces.
Stock-link scope: Complete bearing manufacturers; their products incorporate races. This is not a list of independent race-ring subcontractors.
